T0 at whom 2'25 may concern.

Be it known that I, WARREN F. KAYNOR, a citizen of the United States,and a resident of Waterbury, county of New Haven, and State ofConnecticut, have invented certain new and useful Improvements inv CapButtons, of which the following is a specification.

This invention relates to cap-buttons such as are used on uniform capsfor attaching the ends of the extensible leather straps, commonly wornabove the visors of such caps.

One object of the invention is. to produce a uniform capbutton of thistype in which the button shank may be rigidly secured to the head of thebutton, without the use of solder.

Another object is to produce a uniform cap-button of this type in whichthe. button shank will be supported upon the button back with a highdegree of stability, and in which a portion of the button shank itselfis utilized to positively space the button shell from the button-back.

A further object is to produce a uniform cap-button of this type whichwill be of simple construction, cheap to manufacture, strong, anddurable in use.

With the above and other objects in view, there have been illustrated inthe accom panying drawings, several forms in which the invention may beconveniently embodied in practice.

Fig. 1 is-a perspective view of a uniform cap showing the extensibleleather strap and a cap-button in position.

Fig. 2 is a top View of the shell of a capbutton.

Fig. 3 is a sectional view of one embodiment of the invention showingthe shell, the back and the shank of a button in their relativepositions.

Fig. 4 is a top plan view, with the shell removed, of the button shownin Fig. 3.

Fig. 5 is a perspective view of the buttonshank shown in Figs. 3 andl-detached from the remainder of the button.

Fig. 6 is a sectional view taken alongthe line 6-6 of Fig. 1,illustrating the two wire prongs of the button-shank projecting throughone end of the extensible leather strap, and the cap fabric.

Fig. 7 is a top view of a modified form of shank.

Fig. 8 is a perspective view of the shank illustrated in Fig. 7.

Figs. 9 and 10 are top and perspective views respectively, of anothermodified form of shank.

Figs. 11 and 12 are top and perspective VIEWS respectively, of a stillfurther modified form of shank.

Referring now to the drawings in which like numerals denotecorresponding parts throughout the several views; the body or head ofthe cap-button is composed of a flanged circular disc or back 10, and aface or cylindrical shell 11. The shell 11 may be secured to the back 10in any suitable manner, preferably by swaging. the annular bead 12, ofthe shell around the upstanding flange 13 on the periphery of the back10.

The head of the button is secured to the uniform cap by means of a wireshank whichin the preferred form illustrated in Figs. 3 to 6has a loopedB-shaped configuration, in plan view.

As clearly shown in Figs. 3 t0 6, the loop of the U-shaped wire shank,located within the head of the button, is provided with three horizontalfiatcurved sections 14, 15, 16, in contact with the back 10 to stabilizethe shank in all directions, so that its downwardly projecting prongs17, 17-- which extend through the openings 18, 18 in the back will beperpendicular to the planeof the back. The curved sections 1 1, 15, 1.6areconnected by the raised sections 19, 20,-parallel with the prongs 17,17- and forming contacts for the shell to positively space it from theback. It will thus be seen that the shank-loop between the shell and theback is quite rigid and will resist stresses from all directions. Thereare three contacts with the back and two with the shell.

In operation, whenit is desired to attach the extensible strap to thecap, the prongs 17, 17 of the shank are first inserted through holes inthe leather strap 21 and in the fabric 22 of the cap 23. The prongs 17,17 are then bent over at right angles, as clearly shown at 2 1, 24 inFig. 6, so that they will lie in a straight line just inside the cap,between the fabric 22 and the lining.

Any desired insignia, emblem, or design may be placed upon or formed inthe metal of the shell 11. Moreover, the shell, the

. right angles with one another.

bacln and the shank may be made of any desired size and shape and of anysuitable material, V

In the modified form of shank shown in Figs. 'T'and 8, the wire loop issubstantially circular in plan view, and is-provided with fourhorizontal fiat back-engaging sections 25, 25 26, 26, perpendicular tothe prongs 17, 17. The radial sections 25. 25 are con nected with thesections 26, 26 by the raised sections 27, 28, 29 which form three eqnidistant contact points for the shell 11, As will be seen there are fourcontacts with the back and three with the shell;

In the modified form of shank illustrated in Figs. 9 and 10, the shankloop is sub stantially circular in plan view,being simi lar in thisrespect to the device illustrated in Figs. 7 and S. The back-contacts,30 and 3 as well as the shell-contacts 32 and 33, form This constructiongives a high degree of stability and strength with only two contactswith the back and three with the shell.

Another modified form of the invention is illustrated in Figs. 11 and12. In this embodiment, the shank is provided with a loop having theform of a spiral in plan view. This spiral loop has two portions 34 and85 in contact with the back connected by the raised shell contacts 36and 37, the latter contacts being perpendicular to each other.

It will be obvious that with each form of improved cap-button disclosed,the shank is permanently locked or anchored to the head, and cannot bedislodged from the button back, no matter how much rough handling it mayreceive.

'Moreover, in each embodiment, the shank is provided with a plurality ofsections in contact with the back, and a plurality of raised sections incontact with the shellthus stabilizing the shank, and positively spacingthe shell from the back.

u While there have been disclosed in this specification, several formsin which the invention may be embodied, it is to be understood thatthese forms are shown for the purpose of illustration only: and that theinvention is not to be limited to the specific disclosures but may bemodified and embodied in various other forms without departing fromits'spirit; in short, the invention includes all the modifications andembodiments coming within the scope of the following claims.
